Etymology: Before it named a medical procedure, the root meant simply "to wash." The ancient Greek verb "klyzein" meant to rinse or flush out, and its noun "klystēr" referred to a syringe-like device used for that purpose. Latin borrowed it as "clysterium," and Old French shaped it into "clistere," which passed into Middle English in forms such as "clystere," a spelling used by writers in the later Middle Ages. Medieval and early modern physicians used the term for any liquid injected into the lower bowel, whether for purging or for delivering nourishment or medicine. The word's history is a good example of how medical vocabulary travelled through learned Latin and French into English. Its meaning stayed literal and technical: it described a device or a treatment, not a figure of speech. By the seventeenth and eighteenth centuries, "clyster" was a common term in medical writing, but it gradually fell out of use as the procedure became less common and more specialized terms, such as "enema," took over.
